  • 获取pe文件的文件类型

    工程文件petype.cpp通过调用pefile类中的函数获取文件类型。

    文件类型的判断通过5个监测点完成。

    监测点1：dos头的e_magic

    监测点2：nt头的Signature

    监测点3：文件头的Characteristics

    监测点4：可选头的Magic

    监测点5：可选头的Subsystem

    通过监测点1和2判断是否是pe文件；

    通过监测点3判断文件是否是动态库文件

    通过监测点4判断文件是pe32还是pe32+还是rom映像

    通过监测点5判断文件是否是0环可执行文件[驱动文件]，还是3环可执行文件[exe文件]

    具体代码参见下面：
